Title:
METHOD AND APPARATUS FOR IMPLEMENTING VARIABLE SYMBOL RATE
Document Type and Number:
WIPO Patent Application WO/2010/083716
Kind Code:
A1
Abstract:
A method for implementing variable symbol rate, presetting counters M and N, and M=1, N=0, f being the preset output symbol rate, fs being the frequency of input clock, the method comprises: triggering to judge whether N×f is greater than M×fs at the rising edge of the input clock, if it is, letting the counter M add 1 and outputting a clock pulse; else further judging whether the value of the counter N is equal to fs-1; when N=fs-1, letting the counter N return to 0, and waiting for the next rising edge of the input clock; when N≠fs-1, waiting for the next rising edge of the input clock after letting the counter N add 1; letting the output clock pulse be the system clock, controlling the data to be output to set the symbol rate output.
